Effect of correlated disorder on the magnetism of double exchange systems

G Bouzerar, O Cépas - Physical Review B—Condensed Matter and Materials …, 2007 - APS

[HTML][HTML] Cluster Odd-Parity Multipoles by Staggered Orbital Ordering in Locally Noncentrosymmetric Crystals

S Hayami - Crystals, 2024 - mdpi.com
Odd-parity multipoles in crystals manifest themselves not only in their peculiar electronic
